I don't know if the immunisations are done diffently in england and scotland but here you get hib/men c (1 combined injection) at 12 months and mmr and pcv at 13 months (2 injections)
some children might be a little grumpy afterwards and about 1 in 10 will have a mild flu like reaction a week to 10 days after the mmr.
Most LO's cry a little usually at the second inj but if you quickly pick them up and distract them it is usually short lived
